GAGE @UPZPORT FOR, CRUSHERS.

Application filed January 25, 1928. Serial Ito. 249,283.

'lhis invention relates to certain new and useful improvements in cagesupports for crushers the peculiarities of which will be hereinafterfully described and claimed. a The main object t my invention is toprovide a hinged cage support that will swing outward and backward,leaving an opening in the back of the crusher that will allow the cageto be drawn out without having to remove the cover; secondly, to providea projection on the swing back that will engage and hold the arcuatecage in place in opera- .tion against the circular stress of the rotaryhammers when crushing material between the cage and the hammers;thirdly, to trans- "fer this cage stress from the cover to the backspacer plate; and fourthly, to provide cage-f supporting means ofseparately pivoted members adapted to be securely fastened together tohold the cage in operative position.

In the accompanying drawing on which like reference numerals indicatecorrespond in parts,

ig. 1 represents a vertical sectional view across the shaft of asuitable crusher and cage, with my cage support holding the cage inoperative position;

Fig. 2, a back or rear elevation of half the 36} crusher;

Fig. 3, a sectional view similar to Fig. '1,

- showing the cage support released and the cage freed and ready to mremoved; and

. Fig. 4, a vertical sectional view of half the crusher taken on theline 44 of Fig. 3.

The numeral 1 indicates a horizontal shaft mounted in suitable bearings2 carriedby pedestals on the base plate 3, forming with the upper sideplates and cover 5, a housing 49 for a rotary cylinder comprising a setof spaced discs (Son the shaft, through holes in which discs andeccentric to the shaft, are passed hammer rods 7 on which are pivotally5 mounted rotary heaters or hammers 8,that

operation with a breaker plate 10 and arouate'cage 11 mounted betweensaid base plates of the housing. Said cage of spaced bars or otherwise,is held against an inwardly projecting ledge or shoulder 12 by my cagesupport, that comprises .a swing back spacing plate'13 having at eachside next to the side housing base plate, a flange 14 extending'inwardand having a bearing surface 15 curved to match the contour of the sideribs or edges 16 of said cage, and adapted to support thecrush thematerial fed to a hopper 9,.in co-\ rear portion of the cage when swunginward asshown in Fig. 1. This back plate is hinged on a pivot rod 17passing through the lower part of the flange: 14 near thebottom of theplate, onotherwise, so that the said back plate can swing outward'andpreferably. downward, as shown in Fig. 3, away from its engagement withthe cage. The front and lower part of the cage is held against-the saidshoulderf12 by a separately hinged memconsisting preferably ber of mycage support,

like the flange 14: and

of a bar 18 curved at 19 hinged at its front end on a rod 20 carried by,the side housin or otherwise. This bar 18 is also in duplicate and itsupper edge 19 forms with the bearing edge 15; a continuous support inthe same plane for the respective side edgeroi the cage when in theposition shown in Fig. 1, and swin 's down and releases the cage asshownin ig. 3. The cage can then be removed throu h the open space- 21provided by swinging the back plate outward and downward as indicated inFig. 3. w

The swing back plate is provided on its upper end preferably with aninward lip projection 22, the underside 23 of which is adapted to fitover and lock the rear upper end of the cage to prevent circularmovement of'the cage on the cage support. The upper side 24 of said lipprojection is a curved surface about said pivot rod 17, and makes aclosing engagement with a matching surface 25 at the bottom of thecover, while allowing the swing back plate to open as in Fig. 3..

Fasteningmeans to maintain the bearing surfaces 15 and 19 in supportingengagement with the underside of-- the cage as in Fig. 1, preferablyconsists of a rod 26, hooked i 'or otherwise'pivotally mounted by oneend 27 at the rear end of said bar 18 and extending upward through aboss 28 on the'back plate and threadedfor nuts, whereby the bar 18 theflange 14 and the lOClilIlg lip 22, are all brought into bearingposition and held by tightening said nuts. The rod 26 is preferably indu'plicate,one for each pair of side supports. When inserting the cage,the

front end is held by the front end of the bar 18, and therear is held bythefiange 14; then a door 29 in the back plate gives access to the rods26 which are passed through tapered holes in their respective bosses 28and the nuts applied to bring all said partsinto firmly locked position.A lateral hook 30 on the swing back plate fits a notch 31 and hooks onthe outside of the base plate, and a bolt 32- .so that the shock flange14 and the base plate, fun the back plate to the base plate of thecrushing operation and base plates inthe usual constructhrougli the thersecures cage-supporting means as front and back hinged members, the saidmembers may be otherwise disposed relatively to the. crusher and cagewithout departing from the spirit of my invention.
